Raman spectroscopy and structural properties of InxBi40−xSe60 system

InxBi40−xSe60 (x = 1.6, 4.4, 7, 10 and 13.2) alloys were synthesized by melt-quenching technique. The X-ray diffraction and Raman spectroscopy investigations confirm that the materials are in single phase. Archimedes method and Energy Dispersive Spectroscopy (EDS) have been used for density and chemical characterization of the obtained materials. Indium content dependences of different parameters such as the density (D), the compactness (δ), and the average coordination number (Z) have been investigated and discussed in light of chemical order network and topological models.
